What a wonderful, unique and welcoming B&B. We can only echo what others have said really, if you are looking for a pristine B&B with rigid room access and eating schedules then look elsewhere, if however you want something genuinely charming, quirky, original and properly down-to-earth then this is the place for you.
There's none of the pretense found in some places, you can really, REALLY relax in this beautifully converted old canal storehouse.
We arrived just as Peter was going off to hospital for a hernia operation and were catered for brilliantly by one of his close friends (Chrissie C) who although injured, made us feel utterly at home.
The literature in your room invites you to treat this as a second home and once you come to terms with the relaxed atmosphere, that's exactly what we found ourselves doing. On our first night, we came back from eating out and lit the log burner in the living room and played scrabble until very late. We then slept in until nearly 10 the next morning and were still provided with a lovely cooked breakfast. The room was excellent, the beds were very good quality with crisp cotton bedding, feather duvets and pillows and an array of blankets and throws so you never feel too hot or cold.
The bathroom in our 1st floor bedroom was lovely too, the bath is easily deep enough for two, be warned though that all the cold taps in the house are on an opposite thread to those found everywhere in the world (another lovely quirk).
We visited in mid November so didn't venture out into the garden too much, but the garden is full of various birds including the chickens that laid the eggs we ate at breakfast.
The house is FULL of books, and we loaned a 'Walking in the Brecons' book and an OS map and took an 8 mile walk deep up into the hills from the village of Llanfrynach.
We have five children (that we didn't take with us) and we both thought that we wouldn't want to take any children younger than 8 / 9 years old, just because of the rugged nature of the garden / steps and close proximity of the canal.
The town of Brecon is ten minutes by car, Hay-on-Wye half an hour.
Overall, we are hooked on this place and will be back as and when we can find the spare time.
